A more involved example, leading to a 2-methylbenzofuran derivative, is that of 7-hydroxy-4-methylcoumarin, which is converted to the 7-allyloxy derivative (173) and gives in one stage (concentrated H2S04) the 2,3-dihydrobenzofuran (174) (ring closure followed by opening of the lactone ring).431... 

III rectification stage. Concentrated PMS-lb is separated in the rectification apparatus similar to the one described above. It is distilled under atmospheric pressure into two fractions the head fraction (153-193 °C) and PMS-l,5b (193-195 °C). The head fraction is added to concentrated PMS-lb for further rectification, the tank residue is added to the tank residue of stage I. 

The preconcentrator is a mechanical system used to concentrate the limited mass of explosive delivered from the sample collection subsystem [8], From the sample collection subsystem airflow, the preconcentrator adsorbs explosives (vapor or particulate). The adsorbing surface is then heated to desorb the explosives into the airflow stream for delivery either to a detector or another preconcentration stage. Concentration of the explosives sample occurs because the explosive contained in the sample collection airflow prior to adsorption is now contained in a smaller volume after desorption. Equation 2 shows the relationship between concentration and volumes related to the preconcentrator. 

Concentrate pressure Concentrate pressure can be used to determine the projected pressure drop through the RO system. Projected feed pressure minus the projected first stage concentrate pressure is the projected pressure drop over the first stage. The concentrate pressure from the first stage minus that for the second stage is the projected pressure drop over the second stage.
